| Subject: [PATCH 1/2] kernel/srcu: merge common code into a macro |
| |
| DEFINE_SRCU() and DEFINE_STATIC_SRCU() does the same thing except for |
| the "static" attribute. This patch moves the common pieces into |
| _DEFINE_SRCU() which is used by the the former macros either adding the |
| static attribute or not. |
